According to Jeffrey Wayne Bass, Anuruddha organized the text with an emphasis on the domain of experience (avacara) in which a given type of consciousness may be encountered.
[2] Anuruddha also condensed Abhidhamma teachings by introducing new categories such as "universal" mental factors (sabbacittasadharana), which allowed him to present the material in a much shorter form (in contrast to the Dhammasangani for example).
[2] The Abhidhammattha-sangaha consists of the following chapters:[4] Because of its short length, this text has been difficult to understand, and therefore various commentaries have been written on it:[4] The Abhidhammatthasangaha was first translated into English by Shwe Zan Aung (between 1895 and 1905), and this was revised and edited by Mrs. C.A.F Rhys Davids and first printed in 1910.
The American monk Bhikkhu Bodhi released an updated version with the title "A comprehensive manual of Abhidhamma", with explanations of each section by Ven.
Another translation of the Sangaha by Rupert Gethin and Dr. RP Wijeratne includes the Abhidhammattha-vibhavini commentary by Sumangala and was published in 2002 by the Pali Text Society.
